Sealing and Bearing Elements

Sealing and Bearing ElementsHunger sealing and bearing elements are characterised by an outstanding sealing effect with minimum friction and the exclusion of any metal-to-metal contacts within the hydraulic cylinder, which increases cylinder life. The basic materials used are high-quality plastics and elastomers, which are further refined using special processes. Additives improve the sliding properties and resistance to pressure and abrasion of the end products. Maintenance work during the operational life of the cylinder is thereby considerably reduced.
